Angel, 15, stands to benefit from a new law that allows transgender students to use bathrooms, locker rooms and sports teams of the gender they identify with.

Two of the major players in the passage of California's now-defunct same-sex marriage ban are backing a campaign to overturn a new law allowing transgender students to choose which school restrooms they use and whether to play boys' or girls' sports.

The National Organization for Marriage announced Friday that it was working with another group that is trying to repeal the law at the ballot box. NOM provided early funding and organizing for the 2008 ballot initiative that outlawed same-sex marriages, known as Proposition 8.

Opponents of the transgender student law have until Nov. 8 to gather the 504,760 signatures needed to get a referendum that would nullify the statute on the November 2014 ballot.

The political strategist who ran the successful Proposition 8 campaign, Frank Schubert, has signed on to manage the effort.
